Regenerative Palatal Expander (RPE)
At Fellow Orthodontist, Dr. Lin takes all aspects of the smile and underlying bone structure into account when creating personalized treatment plans.
Through this holistic S.H.A.P.E. philosophy, we use specialized orthopedic appliances to guide healthy jaw and facial development, helping prevent severe misalignments and supporting healthy breathing, function, and long-term facial harmony.
For many young patients, that journey begins with the Regenerative Palatal Expander (RPE).
Regenerative Palatal Expander: What is it?
The Regenerative Palatal Expander (RPE), traditionally known as a Rapid Palatal Expander or RPE, is a custom-made dentofacial orthopedic appliance.
It’s designed to gently guide upper jaw development during childhood and adolescence, while the bones are still growing.
The device is anchored to the upper molars and includes a small plate that sits in the palate, with a small center screw that’s turned at home using a special key.
Rather than rapidly widening the jaw, these small, controlled adjustments encourage gradual, regenerative expansion and healthy skeletal development over time.
A narrow palate can contribute to a variety of issues, including crossbites, constricted airflow, sleep disorders (such as sleep apnea), snoring, mouth breathing, receded or underdeveloped jaws, and facial imbalance.
By guiding expansion at the right time, we can support healthy jaw development, improve airflow and breathing, create the space needed for proper tooth alignment, promote long-term bite health, and encourage facial harmony.
Dentofacial Orthopedics: A Holistic Approach to Growth
At Fellow Orthodontist, we view palate expansion as more than creating space for teeth.
Regenerative Palatal Expansion (RPE) is a form of dentofacial orthopedic treatment that guides healthy jaw growth and facial development during childhood, supporting proper function, breathing, and long-term facial harmony, not just straightening teeth.
Who would need an RPE?
This technique is effective only while the mid-palatal suture is still soft and flexible, which is why RPE orthodontics is recommended for children and pre-teens, usually between ages 6 and 13.
(However, Dr. Lin also performs expansion treatment for adults, which you’ll read about further down the page.)
RPE may be recommended when the upper and lower jaws are not developing in harmony, resulting in crowding, bite issues, or functional concerns.
Dr. Lin may recommend a palatal expander to address:
- Moderate to severe crowding
- A posterior crossbite (upper teeth sit inside lower teeth in the back)
- Breathing issues related to a narrow nasal passage
- Impacted teeth due to lack of space
- Narrow smile or facial asymmetry
What to Expect with Palate Expansion
- Initial evaluation: When you and your child visit us for your initial consultation, Dr. Lin will perform a detailed clinical exam, taking a high-quality 3D x-ray and 3D rendering of their teeth and bite, to assess their growth and treatment needs.
- Custom fabrication: If a palate expander is the best treatment route, the device will be custom-made and fitted to your child’s upper molars. We’ll show you how to activate the device and how to care for it, and ensure that you feel comfortable.
- Activation phase: You’ll turn a small key once or twice a day for 1–3 weeks, following Dr. Lin’s exact instructions.
- Retention phase: Once the palate has reached the desired width, the expander stays in place for a few months to allow the new bone to stabilize.
- Next steps: Depending on your child’s needs, this phase may be followed by braces or Invisalign® to align the teeth.
Most children adapt to the palatal expander quickly. Some may feel minor palate expander side effects, like a tingling sensation or temporary pressure in the nose or upper jaw, but this usually fades after the first few turns. Throughout the process, we’ll be here to answer all of your questions, every step of the way.
Are there palatal expanders for adults?
For patients whose growth plates have already fused (typically older teens and adults), a different approach is needed.
In those cases, Dr. Lin may recommend a MARPE or MSE device — a more advanced appliance designed to expand the jaw with the help of TADs (temporary anchorage devices) which he personally places.
Dr. Lin collaborates with a highly-experienced ent/os surgeon, if we need to perform a special procedure called DOME. This procedure helps release the sutures, so we can effectively expand adults the same way we can expand children.
